Hi
Is the CMOS Coin Cell battery in good condition, recently fitted?
Is the main battery kept charged?

Hi
Next is to check your storage device I believe.
NB: Daft idea, is the time, date and region set to manual or auto?

Hi,
Thanks. To clarify: I’m using a SATA drive, and its health/status appears normal with no visible issues so far.
Time, date, and region are already set to automatic.
Given this, what would you suggest checking next?

Hi
Well I would have ensured I removed Microsoft from the equation.
Create and Boot with a Live LINUX Mint USB, when the problem shows up.
This Divides the problem into Hardware issue, because it is not booting Winows, and a software issue if the boot problem persists with another OS, Linux Mint.
Given the 10 minute time lag I wonder if it is performing a disk check in the background?

@anne_droid Hi,
Btw, thanks for suggestion
To clarify, the system is not hanging during boot. The failure happens before POST.
Each time I press the power button, only the Caps Lock LED turns on for ~3 seconds and then the laptop goes completely dead again. Repeating this cycle multiple times over 5–10 minutes eventually allows the EC to complete power initialization and the system finally turns on.
This occurs before BIOS or any boot device is accessed, so no OS, disk, or filesystem activity is involved. Once the laptop powers on, it boots normally.
I ve confirmed this is a hardware power-initialization issue: the CPU fan has failed, and the previous Dell charger died due to a DC-side cable short (brick → pin), which likely stressed the DC-in/EC circuitry. Because the issue is at EC/power-rail level, testing with another OS wouldn’t isolate it.
